Functional Family Therapy (FFT) (Sexton & Alexander, 2006, Sexton, 2009) is an evidence-based treatment program for adolescents with behavior problems. FFT is a highly intense yet short-term intervention in which family-based treatment usually occurs in 12 to 20 family sessions over the course of 4 to 8 months. The active ingredients of FFT are based upon theoretically derived constructs that mediate the relationship between initial youth and family risk factors and successful treatment outcomes (e.g., decrease in drug use, risky sexual behavior, and other conduct problems).
